I came across some nifty instructions for making those creepy Blair Witch stick figures to hang from trees (or gutters in my case). Here's a link in case someone else was thinking of the same thing:
I was hiking off-trail in the woods last autumn and came across a few someone had randomly strung up...it was quite spooky (the weird quietness of the forest accentuated this) and my friend and I didn't hang around, even though we had previously done the same thing at an old camp site one summer, lol! Good times.
